Hereinafter, the present invention will be described in detail byexplaining exemplary embodiments of the invention with reference to theattached drawings. The same reference numerals in the drawings denotelike elements, and a repeated explanation thereof will not be given.

As shown in FIG. 1, an embodiment of the present invention relates to apallet for goods 100 (hereinafter referred to as the ‘pallet’) and a boxassembly 1 (hereinafter, referred to as the ‘box assembly’) includingthe pallet 100.

The box assembly 1 may include a box 200 provided in a foldable form,the pallet 100 arranged below the box 200, and a cover member 300installed on the box 200.

The cover member 300 may include a cover body portion 310 provided witha plate shape, an outer frame 320 that surrounds an external portion ofthe cover body portion 310, and a supporting leg support 350 installedon an upper surface of the cover body portion 310.

When the box assemblies 1 are stacked as a plurality of layers, asupporting leg 150 of the pallet 100 of the box assembly 1 at anuppermost layer may be inserted into the supporting leg support 350installed on the cover member 300 of the box assembly 1 at a lowermostlayer to fix a position of the supporting leg 150.

The outer frame 320 of the cover member 300 may include edge frames 3210that are longitudinally arranged along an edge of the cover body portion310 and corner connection portions 3220 that are arranged atintersection corner portions of the edge frames 3210 and connect theedge frames 3210 arranged to cross each other.

A detailed structure of the cover member 300 will be described below.

The foldable type box 200 may be provided below the cover member 300.

The box 200 may include a plurality of plate portions 210 and aplurality of frame portions 220 that surround an external portion of theplate.

Here, the frame portion 220 may include horizontal frames 221 andvertical frames 222.

A foldable frame 230 may be installed between the vertical frame 222 andthe adjacent vertical frames 222 to fold the box 200.

A handle portion 240 may be provided on the plate portion 210 and, thus,a worker may grip the handle portion 240 and may hold the box assembly1.

As shown in FIGS. 1 and 2, the pallet 100 may be installed below the boxassembly 1.

A lower edge of the box 200 is accommodated in an installation portion(not shown) installed on the pallet 100 and, thus, the box 200 may beinstalled and fixed on the pallet 100.

As shown in FIG. 2, the pallet 100 may include a pallet body portion110, an outer frame 120 that surrounds an external portion of the palletbody portion 110, and the supporting leg 150 installed on a lowersurface of the pallet body portion 110.

The supporting leg 150 may include a plurality of support legs that arespaced apart from each other on the lower surface of the pallet bodyportion 110.

Although FIG. 2 illustrates the case in which nine supporting legs arepresent, one leg is arranged in a central portion, and eight legs arearranged at edge portions, respectively, it would be understood that thenumber is changed according to the size of the box assembly 1 or thepallet 100.

Each of the supporting legs 150 may include a plurality of unitsupporting legs 151 and a flange portion 152 that extends in an outwarddirection thereof.

One supporting leg 150 may be divided into the plurality of unitsupporting legs 151 to distribute load and, even if one unit supportingleg 151 breaks and is not capable of functioning, the other intact unitsupporting legs 151 may function as a support.

Conventionally, a supporting leg is provided with a single tube shape (atruncated quadrangular pyramid shape) and, thus, when the supporting legbreaks and does not function as a support due to shock, there is aproblem in that a box assembly is crooked and is entirely inclined.

As such, when any one of supporting legs breaks and is not capable offunctioning, an entire pallet needs to be replaced.

However, according to the present invention, the supporting leg 150 mayinclude the plurality of unit supporting leg 151 and, thus, even if anyone of the unit supporting legs 151 breaks, the other unit supportinglegs 151 may function as a support.

The supporting leg is divided into a plurality of legs and, thus, loadis appropriately distributed to support relatively heavy goods comparedwith the conventional supporting leg provided with a single tube shape.

In addition, the supporting leg 150 is coupled to the pallet bodyportion 110 rather than being integrated with the pallet body portion110 and, thus, when one supporting leg 150 completely breaks and doesnot function as a support, only the corresponding portion may beadvantageously replaced.

The supporting leg 150 may include the flange portion 152.

The flange portion 152 is a region with a coupling member (not shown)coupled thereto when the supporting leg 150 and the pallet body portion110 are connected or the supporting leg 150 and the outer frame 120 areconnected.

Accordingly, the flange portion 152 may be provided to surface-contact alower surface of the pallet body portion 110 or a lower surface of theouter frame 120.

An extension length of the flange portion 152 may be changed accordingto a region of the pallet body portion 110, on which the supporting leg150 is installed.

For example, in the case of the supporting leg 150 (150 a) installed onthe center of the pallet body portion 110, an extension length of theflange portion 152 may be uniform in all directions.

When the supporting leg 150 (150 b) is positioned at a corner region ofthe pallet body portion 110, an extension length of the flange portion152 in a direction toward two sides forming the corresponding corner maybe greater than an extension length of the flange portion 152 in adirection toward other portions.

In addition, the flange portion 152 of the supporting leg 150 (150 c)installed on an intermediate portion of an edge of the pallet bodyportion 110 may extend with a relatively great length in an outer edgedirection, i.e., in one direction and may extend with a relatively smalllength in the other three directions.

Ribs 1521 that are separated from each other may be formed on a lowersurface of the flange portion 152 and, in this regard, the ribs 1521 mayreduce a weight and ensure strength while maintaining a thickness of theflange portion 152 to some extent.

As shown in FIG. 3, the cover member 300, the box 200, and the pallet100 may be detachably provided.

An edge of a lower surface of the cover member 300 may be accommodatedin an edge of an upper surface of the box 200, and an edge of a lowersurface of the box 200 is accommodated in an edge of an upper surface ofthe pallet 100 to complete assembly.

To this end, the outer frame 320 of the cover member 300 may includeupper accommodation grooves 3213 and 3223 (refer to FIG. 17) into whichan upper edge of the box 200 is inserted and accommodated and the outerframe 120 of the pallet 100 may also include lower accommodation grooves1213 and 1223 into which a lower edge of the box 200 is inserted andaccommodated.

The foldable frames 230 of the box 200 may be provided and arranged atcorners of the box 200 and front and rear portions of the box 200 withrespect to FIG. 3, respectively. The handle portions 240 may be arrangedat upper portions of opposite lateral surfaces of the box 200.

The supporting leg supports 350 formed on an upper surface of the covermember 300 may be arranged on a central portion, corners, andintermediate portions of an edge of the cover body portion 310, whichmay be changed according to the size of the box assembly 1.

An uppermost surface of the pallet body portion 110 of the pallet 100may be formed in a planar shape, only portions of the pallet bodyportion 110, at which the supporting leg 150 is positioned, may beopened, and cavities 1511 in the supporting legs may be viewed throughthe opened portions.

The cavities 1511 are exposed upward and, thus, the plurality of pallets100 may be accumulated and stacked.

The cavities 1511 may be formed in the unit supporting legs 151,respectively.

Coupling members (not shown) may be installed around the supporting leg150 to couple the supporting leg 150 and the pallet body portion 110 andto couple the supporting leg 150 and the outer frame 120.

The supporting legs 150 installed on the pallet 100 may be arranged on acentral portion, corners, and intermediate portions of an edge of thepallet body portion 110, which is changed according to the size of thebox assembly 1.

Although the drawing illustrates a box assembly with a square plane of,for example, 1140 mm×1140 mm, it would be understood that a box assemblyshaped like a square plane and a rectangular plane with a small or largesize is within the scope of the present invention.

FIG. 4 is a detailed diagram of an exploded perspective view shown inFIG. 3.

Here, the box 200 may include a plate portion 210 and a frame 220 thatsurrounds the plate portion 210.

The frame 220 may be re-divided into the vertical frame 222 and thehorizontal frame 221.

The foldable frame 230 may be provided between the vertical frame 222and the vertical frame 222 at a folded region of the box 200 and mayconnect neighboring vertical frames 222 coupled to the plate portions210.

As shown in a right enlarged circle of FIG. 4 in detail, the foldableframe 230 that is arranged in a perpendicular direction may be installedbetween the vertical frame 222 installed on the left plate portion 210and the vertical frame 222 installed on the right plate portion 210.

A side end of the vertical frame 222 may be slidably coupled to a sideend of the foldable frame 230.

To this end, the side end of the vertical frame 222 and a side end ofthe foldable frame 230 may be embodied as male and female slide rails.

A left enlarged circle of FIG. 4 shows a state in which a lower edge ofthe box 200 is inserted into and accommodated in the lower accommodationgrooves 1213 and 1223 provided in the outer frame 120 of the pallet 100.

All of the upper accommodation grooves 3213 and 3223 (refer to FIG. 17)of the cover member 300 or the lower accommodation grooves 1213 and 1223of the pallet 100 may be provided in the form of a continuous groovealong an edge and may be shaped to correspond to the shape of the box200.

That is, the lower accommodation grooves 1213 and 1223 and the upperaccommodation grooves 3213 and 3223 may form a continuous closed loopalong sides and corners of upper surfaces of the outer frames 120 and320.

As such, a box edge is inserted into and caught by the loweraccommodation grooves 1213 and 1223 and the upper accommodation grooves3213 and 3223 and, thus, the cover member 300 or the pallet 100 may beprevented from being separated from the box in a horizontal direction.

FIG. 5 is a perspective view of a state in which the pallet 100 isassembled.

As shown in FIG. 5, the outer frame 120 is installed at an edge of thepallet body portion 110.

The outer frame 120 may include edge frames 121 installed at sides of anedge of the pallet body portion 110 and a corner connection portion 122that is positioned at a corner portion of the pallet 100 and connectsthe two edge frames 121 arranged to cross each other.

A first boundary region 121 a provided with an inclined shape and asecond boundary region 121 b that is connected to the first boundaryregion 121 a and extends in an outward direction may be provided at anend of the edge frames 121.

The first boundary regions 121 a of the two edge frames 121 that areadjacent to each other and are perpendicularly arranged to each othermay contact and face each other.

The second boundary regions 121 b of the two edge frames that areadjacent to each other and are perpendicularly arranged to each othermay be spaced apart from each other and a corner space CS (refer to FIG.6) may be formed between the second boundary regions 121 b.

As shown in FIG. 6, the corner connection portion 122 may be positionedin the corner space CS.

The edge frame 121 may include a lower accommodation groove 1213, anexternal wall 1211 positioned outside the lower accommodation groove1213, an internal wall 1212 positioned inside the lower accommodationgroove 1213, and a bottom wall 1214 positioned below the loweraccommodation groove 1213.

In addition, the corner connection portion 122 may also include a loweraccommodation groove 1223, an external wall 1221 positioned outside thelower accommodation groove 1223, an internal wall 1222 positioned insidethe lower accommodation groove 1223, and a bottom wall 1224 positionedbelow the lower accommodation groove 1223.

The corner connection portion 122 may connect the edge frames 121 thatare adjacent to each other.

Thereby, the lower accommodation groove 1213 of the edge frame 121 andthe lower accommodation groove 1223 of the corner connection portion 122may be connected to each other, the internal wall 1212 of the edge frame121 and the internal wall 1222 of the corner connection portion 122 maybe connected to each other, and the external wall 1211 of the edge frame121 and the internal wall 1222 of the corner connection portion 122 maybe connected to each other.

Accordingly, the box 200 may be stably accommodated in the loweraccommodation groove 1213 of the edge frame 121 and the loweraccommodation groove 1223 of the corner connection portion 122.

Space portions 1221 a, 1222 a, and 1222 b may be formed in each of theinternal wall 1222 and the external wall 1221 of the edge frame 121 anda protrusion 1225 may be provided on the corner connection portion 122.

Accordingly, when the corner connection portion 122 is positioned in thecorner space CS, the protrusion 1225 may be inserted into the spaceportions 1221 a, 1222 a, and 1222 b of the internal wall 1212 and theexternal wall 1211 of the edge frame 121.

Although not shown, a space portion may be formed in the cornerconnection portion 122 and a protrusion may be formed on the edge frame121 or vice versa.

As such, in a state in which the edge frame 121 and the cornerconnection portion 122 are coupled, a coupling member 123 may beinserted in a direction toward the corner connection portion 122 and,then, is deeply inserted and is coupled in a direction toward the edgeframe 121.

Thereby, the edge frame 121 and the corner connection portion 122 may befixed to each other.

As shown in FIGS. 5 and 6, an uppermost surface of the pallet 100 may beformed in a planar shape and only a portion of the pallet 100, at whichthe supporting leg 150 is installed, may be exposed through upperportions of the cavities 1511.

Here, an area ratio of the cavities 1511 may be small compared with anentire area of a pallet.

Accordingly, the possibility that most goods enter the cavities 1511 maybe low and most goods may be stably positioned. In addition, thecavities 1511 are separated in equal number to the number of the unitsupporting legs 151 and, thus, an area of an entrance is small comparedwith a cavity of a supporting leg provided with a single tube shapeaccording to the related art.

FIG. 7 is a diagram showing the pallet 100 according to a firstembodiment of the present invention.

The pallet 100 may largely include the pallet body portion 110, theouter frame 120, and the supporting leg 150. For clear illustration, thesupporting leg 150 and the coupling member 123 (refer to FIG. 6) forcoupling the supporting leg 150 are omitted from the drawing.

According to the first embodiment of the pallet 100 shown in FIG. 7, thepallet body portion 110 may include a honeycomb member 111 at a centralportion thereof, and an upper surface panel 112 and a lower surfacepanel 113 that are positioned on an upper surface and a lower surface ofthe honeycomb member 111 to cover the upper and lower surfaces.

The upper surface panel 112, the honeycomb member 111, and the lowersurface panel 113 may be coupled to form the pallet body portion 110,the outer frame 120 may be installed outside the pallet body portion 110and, then, the coupling member 163 (refer to FIG. 15) for fixing thesupporting leg 150 (refer to FIG. 5) to the pallet body portion 110 andthe outer frame 120 may be required.

The coupling member 163 (refer to FIG. 15) may include a screw, a rivet,or the like and objects corresponding to shapes of spaces divided fromthe honeycomb member 111 may be inserted and fixed around the firstthrough hole 111 a to be coupled to the coupling member 163 and tofunction as a nut or a support.

This may be defined as a fixation member 170 a.

When spaces divided from the honeycomb member 111 are shaped like ahexagon, the fixation member 170 a may have a hexagonal shape. However,the fixation member 170 a may be provided with other shapes.

Through holes 111 a, 112 a, and 113 a may be installed to be spacedapart from each other in central portions and edge portions of thehoneycomb member 111, the upper surface panel 112, and the lower surfacepanel 113.

For convenience of description, the through hole formed in the honeycombmember 111 is defined as the first through hole 111 a, the through holeformed in the upper surface panel 112 is defined as the second throughhole 112 a, and the through hole formed in the lower surface panel 113is defined as the third through hole 113 a.

A fixation member 170 a according to the first embodiment may bearranged around the first through hole 111 a.

For example, a minimum of four fixation members 170 a may be arrangedalong four sides of the first through hole 111 a around the firstthrough hole 111 a at a central portion and a minimum of two fixationmembers 170 a may be arranged along two internal sides of the firstthrough hole 111 a around the first through hole 111 a at a cornerportion.

In addition, a minimum of three fixation members 170 a may be arrangedalong three internal sides of the first through hole 111 a around thefirst through hole 111 a at an intermediate portion of an outer edge ofthe honeycomb member 111.

A coupling guidance hole 113 b may be formed around the third throughhole 113 a of the lower surface panel 113 to allow the coupling member163 (refer to FIG. 15) to pass through the coupling guidance hole 113 b.

The fixation member 170 a may not be installed at two external sidesaround the first through hole 111 a at a corner portion and an externalside of the first through hole 111 a at an intermediate portion of anouter edge of the honeycomb member 111.

In this case, the coupling member 163 may be coupled directly to theouter frame 120.

Although described below, an insertion space 1215 into which an outeredge of the honeycomb member 111 is inserted may be formed in the edgeframe 121 included in the outer frame 120.

The insertion space 1215 may be formed by the internal wall 1212, anupper extension 1215 a that extends in an inward direction (in adirection toward an edge of a honeycomb member) from an upper surface ofthe internal wall 1212, and a lower extension 1215 b that extends in aninward direction (in a direction toward an edge of a honeycomb member)from a lower surface of the internal wall 1212.

Accordingly, an outer edge of the honeycomb member 111 may be insertedinto and fixed to the insertion space 1215.

In this state, the corner connection portion 122 may be arranged in anintersection direction and arranged in a corner space between the twoadjacent edge frames 121 to connect the two edge frames 121.

FIG. 8 is a diagram showing the pallet 100 according to a secondembodiment of the present invention.

The first embodiment shown in FIG. 7 and the second embodiment shown inFIG. 8 are different from each other in that each fixation member 170 ais configured in a small block form to correspond to a divided space ofthe honeycomb member 111 according to the first embodiment but thefixation members 170 a are continuously arranged at an edge of a firstthrough hole 111 b according to the second embodiment.

However, a configuration of a fixation member opposite to an outer edgeof the honeycomb member 111 may be omitted because the coupling member163 (refer to FIG. 15) is coupled directly to the outer frame 120.

For example, the ‘

’-shaped fixation member 170 b may be installed around the first throughhole 111 b at a center.

The ‘

’ or ‘

’-shaped fixation member 170 b may be installed at four corner portions.In addition, the ‘

’-shaped fixation member 170 b may be installed at four intermediateportions of an outer edge.

Except for the above description, the second embodiment is the same asthe first embodiment and, thus, a repeated description will be not givenhere.

FIG. 9 is a diagram showing the pallet 100 according to a thirdembodiment of the present invention.

The first embodiment shown in FIG. 7 and the second embodiment shown inFIG. 8 are different from the third embodiment shown in FIG. 9 in thatall fixation members 170 c are ‘

’-shaped and are arranged around first through holes 111 c,respectively.

In this case, all the fixation members 170 c are manufactured in thesame shape to reduce manufacturing costs compared with in the secondembodiment.

To this end, the honeycomb member 111 may be provided with a ‘#’-shape.

Except for the first through hole 111 c at a center, the first throughholes 111 c at corner portions and the first through holes 111 c atintermediate portions of an edge may be opened in an outer direction.

When the fixation members 170 c are installed on the honeycomb member111 and the outer frame 120 is coupled, portions of the fixation members170 c at an edge of the honeycomb member 111 (which is an edge portionat which a fixation member is not installed) and corners and anintermediate portion of an edge of the honeycomb member 111 may beinserted and fixed to the insertion space 1215 of the outer frame 120.

Except for the above description, the third embodiment is the same asthe first and second embodiments and, thus, a repeated description willbe not given here.

FIGS. 10A to 10C are diagrams showing a configuration of the outer frame120.

FIGS. 10A and 10B are diagrams showing a state in which the edge frame121 and the corner connection portion 122 are coupled in the outer frame120.

In a state in which the edge frame 121 and the corner connection portion122 are coupled, the edge frames 121 and the corner connection portion122 may be continuously connected via surface to surface contact.

That is, the lower accommodation groove 1213 of the edge frames 121 andthe lower accommodation groove 1223 of the corner connection portion 122are continuously connected, the external wall 1211 of the edge frames121 and the external wall 1221 of the corner connection portion 122 arecontinuously connected, and the internal wall 1212 of the edge frames121 and the internal wall 1222 of the corner connection portion 122 arecontinuously connected.

Here, inclination surfaces 1212 f and 1222 f that are inclined towardthe lower accommodation grooves 1213 and 1223 may be formed at an upperedge of the internal wall 1212 of the edge frames 121 and an upper edgeof the internal wall 1222 of the corner connection portion 122.

When a lower edge of a box enters the lower accommodation grooves 1213and 1223, the lower edge may be in contact with the inclination surfaces1212 f and 1222 f to be smoothly moved in a direction toward the loweraccommodation grooves 1213 and 1223.

FIG. 10C is a perspective view of the corner connection portion 122.

The internal wall 1222 and the external wall 1221 of the cornerconnection portion 122 may be each bent in a shape of ‘

’ on a plane view and the lower accommodation groove 1223 between theinternal wall 1222 and the external wall 1221 may also be bent in ashape of ‘

’ on a plane view.

The protrusion 1225 may be provided on an inner surface of the internalwall 1222 and may be a portion inserted into a lateral surface of theedge frame 121.

The protrusions 1225 may be arranged toward different parts to becoupled to the edge frames 121 in different directions, respectively.

Each of the protrusions 1225 may include a first protrusion 1225 a and asecond protrusion 1225 b, an separation space 1225 c shaped like a slitmay be formed between the first and second protrusions 1225 a and 1225b, and a space portion 1225 d shaped like a circle may be formed at acenter of the interval portion.

A height of the first protrusion 1225 a may be greater than a height ofthe second protrusion 1225 b and an upper lateral surface of the firstprotrusion 1225 a may be inclined to smoothly couple the firstprotrusion 1225 a and the second protrusion 1225 b to each other becausean internal height of a first space portion 1212 a on the internal wall1212 of the edge frames 121 is higher than a height of a second spaceportion 1212 b and the upper lateral surface is inclined.

The separation space 1225 c between the first and second protrusions1225 a and 1225 b may be a portion into which a separation rib 1212 c inthe internal wall 1212 of a lateral surface of the edge frames 121 isinserted and the space portion 1225 d shaped like a circle (or shapedlike a C) may be a portion into which the coupling member 123 (refer toFIG. 12) for coupling the edge frames 121 and the corner connectionportion 122 is inserted.

For insertion of the coupling member 123, at different surfaces of thecorner connection portion 122, an external insertion hole 1221 a may beformed in the external wall 1221, an internal insertion hole 1222 a maybe formed in the internal wall 1222, and an insertion guidance channel1223 a, a bottom of which is dug down, may be provided between theexternal insertion hole 1221 a and the internal insertion hole 1222 a.

The insertion guidance channel 1223 a may be formed in such a way thatthe bottom wall 1224 of the lower accommodation groove 1223 is slightlydug down.

In addition, the two insertion guidance channels 1223 a may be arrangedto cross each other.

The internal insertion hole 1222 a may be connected to theaforementioned circular space portion 1225 d.

FIG. 11A is a side view of the corner connection portion 122 and FIG.11B is a side view of the edge frame 121 coupled thereto.

As shown in FIG. 11A, the lower accommodation groove 1223 may beprovided between an internal wall and the external wall 1221 of thecorner connection portion 122 and the bottom wall 1224 may be providedbelow the lower accommodation groove 1223.

Space portions may be formed in the external wall 1221, the internalwall 1222, and the bottom wall 1224, respectively, to enhance strengthand reduce weight.

The aforementioned inclination surface 1222 f may be formed on the upperedge of the internal wall 1222.

The separation space 1225 c may be formed between the first protrusion1225 a and the second protrusion 1225 b and the space portion 1225 dshaped like a circle (or shaped like a C) may be formed in theseparation space 1225 c.

As described above, the internal insertion hole 1222 a and the spaceportion 1225 d shaped like a circle (or shaped like a C) may beconnected and, in this case, an internal diameter of the internalinsertion hole 1222 a may be smaller than an internal diameter of thespace portion 1225 d shaped like a circle (or shaped like a C).

This configuration may be used to catch a head portion 123 a of thecoupling member 123 (refer to FIG. 12) that enters the internalinsertion hole 1222 a through the external insertion hole 1221 a toprevent the coupling member 123 from entering inward any farther.

The edge frame 121 may also include the external wall 1211, the internalwall 1212, the lower accommodation groove 1213, and the bottom wall 1214below the lower accommodation groove 1213.

The upper extension 1215 a and the lower extension 1215 b may extend inan inward direction (in a direction toward a honeycomb member) fromupper and lower surfaces of the internal wall 1212.

The insertion space 1215 may be formed between the upper extension 1215a and the lower extension 1215 b and an edge of the honeycomb member 111(refer to FIG. 7) may be inserted into the insertion space 1215.

The inclination surface 1212 f may also be formed on an upper edge ofthe internal wall 1212 of the edge frames 121 to form a downwardinclination surface in a direction toward the lower accommodation groove1213.

A space portion of the internal wall 1212 may be divided into the firstspace portion 1212 a and the second space portion 1212 b, and the firstspace portion 1212 a and the second space portion 1212 b may beseparated by the separation rib 1212 c.

A fixation portion 1212 d to which a body portion 123 b of the couplingmember 123 (refer to FIG. 12) passing through the corner connectionportion 122 is inserted and fixed may have a C-shape in the separationrib 1212 c.

An internal height of the first space portion 1212 a in the internalwall 1212 of the edge frames 121 may be higher than a height of thesecond space portion 1212 b.

The height of the second space portion 1212 b is smaller than the heightof the first space portion 1212 a because a thickness of a bottom wallof the second space portion 1212 b is greater than a thickness of abottom wall of the first space portion 1212 a.

As such, the thickness of the bottom wall of the second space portion1212 b is thick to arrange the flange portion 152 of the supporting leg150 below the second space portion 1212 b and to stably couple a bodyportion 163 b of the coupling member 163 (refer to FIG. 15) of thesupporting leg 150 passing through the flange portion 152 to the bottomwall of the second space portion 1212 b in the future.

If the bottom wall of the second space portion 1212 b is thin like thebottom wall of the first space portion 1212 a, there is a problem inthat the coupling member 163 is externally separated and, thus,supporting of the supporting leg 150 is released due to weak force ofthe coupling member 163 of the supporting leg 150, which attracts thebody portion 163 b.

As shown in FIG. 12, in a state in which the corner connection portion122 is inserted between the edge frames 121 arranged to cross eachother, the coupling members 123 may be inserted.

The coupling members 123 may also be inserted to cross each other.

The coupling member 123 may connect the corner connection portion 122and the edge frames 121 through the external insertion hole 1221 a, theinsertion guidance channel 1223 a, and the internal insertion hole 1222a of the corner connection portion 122.

In more detail, as shown in FIG. 13, one coupling member 123 may bemoved toward the external insertion hole 1221 a, the insertion guidancechannel 1223 a, and the internal insertion hole 1222 a

In particular, the body portion 123 b (a screw thread is formed on anouter circumferential surface of the body portion 123 b) of the couplingmember 123 may pass through the internal insertion hole 1222 a and thecircular space portion 1225 d shown in FIGS. 10 and 11 and, then, may becoupled to the fixation portion 1212 d on the internal wall 1212 of theedge frame 121 shown in FIG. 12.

However, a diameter of the head portion 123 a of the coupling member 123is greater than that of the body portion 123 b and, thus, the headportion 123 a may be caught by an edge of the internal insertion hole1222 a formed in the internal wall 1222 of the corner connection portion122, may not enter any farther, and may be fixed at a current location.

When one coupling member 123 is completely coupled using the abovemethod, another coupling member 123 that is inserted to cross the formercoupling member 123 may be coupled in the same way.

Needless to say, although the two the coupling members 123 are coupledto cross each other, locations at which the coupling members 123 arecompletely coupled may be lastly spaced apart from each other withoutinterfering with each other. This is because the internal insertionholes 1222 a formed in one corner connection portion 122 are adjacent toeach other while being spaced apart from each other.

The first boundary regions 121 a of the two edge frames 121 may contacteach other and the unit supporting leg 151 included in the supportingleg 150 may be arranged on the pallet body portion 110 to position thecavities 1511.

A rib 1512 may be formed in each of the cavities 1511 and portions ofthe rib 1512 may be provided to cross each other to enhance strength.

FIG. 14 is a diagram showing the supporting leg 150.

As described above, the supporting leg 150 may include a plurality ofunit supporting legs 151 and the flange portion 152 that extends in alateral direction of the supporting leg.

An uppermost portion of the supporting leg 150 may protrude slightlyupward compared with the flange portion 152 to be inserted into throughholes 110 a; 111 a, 112 a, and 113 a of the pallet body portion 110.

In addition, coupling holes 152 a may be formed in the flange portion152 and, thus, the coupling members 163 (refer to FIG. 15) for couplingthe supporting legs 150 and the pallet body portion 110 may be insertedinto the coupling holes 152 a.

An upper surface of the flange portion 152 may be provided with a smoothplane shape and, as shown in FIG. 2, a lower surface of the flangeportion 152 may be divided by the ribs 1521 (refer to FIG. 2).

An extension length of the flange portion 152 that extends from thesupporting leg 150 (150 a) at a center may be uniform in all directions.

An extension length of the flange portion 152 that extends from thesupporting leg 150 (150 b) at each corner portion may be longer thanother portions to increase a supporting area.

The outer frame 120 needs to be coupled to a portion of the flangeportion 152, which extends in a direction toward an edge, and, thus, aportion that extends in an edge direction needs to be wider than otherportions to smoothen coupling and distribute load.

Viewed from above, a plurality of unit supporting legs 151 is separatedand, thus, an entrance area of the cavity 1511 may also be reduced inequal number to the separated number.

Accordingly, goods except for goods with a smaller size than an entrancearea of the cavity 1511 of the unit supporting leg 151 may be preventedfrom entering the cavity 1511.

Here, each of the unit supporting legs 151 may have a truncatedquadrangular pyramid shape and a lateral corner 151 a may be shaped likean inclination surface or a chamfer.

FIG. 15 is a side view showing a state in which the pallet body portion110, the outer frame 120, and the supporting leg 150 are coupled on thepallet 100.

The case in which the supporting leg 150 (150 b/150 c) arranged to beadjacent to an outer side, i.e., an edge side of the pallet body portion110 is fixed will be described below.

A relatively long extension portion of the flange portion 152 of thesupporting leg 150 may be closely attached to a lower surface of theouter frame 120 and a relatively short extension portion may be closelyattached to a lower surface of the pallet body portion 110.

The coupling member 163 may be coupled to the fixation members 170; 170a to 170 c that are each installed at the honeycomb member 111 and theinternal wall 1212 of the edge frames 121 of the outer frame 120.

The coupling member 163 may be provided in the form of a screw and mayinclude a head portion 163 a and the body portion 163 b with a screwthread formed on an outer circumferential surface thereof.

The coupling member 163 that is lastly fixed to the outer frame 120 maypass through the flange portion 152 of the supporting leg 150 and, then,may be installed through a bottom wall of the second space portion 1212b of the internal wall 1212 of the edge frames 121.

In addition, the head portion 163 a may be caught by and fixed to alower surface of the flange portion 152.

As described above, the bottom wall of the second space portion 1212 bis formed to be thicker than other parts to support the body portion 163b of the coupling member 163 by a relatively wide area.

The coupling member 163 that is lastly fixed to the fixation members 170installed on the honeycomb member 111 may be inserted into the lowersurface panel 113 and the fixation members 170 through the flangeportion 152.

The head portion 163 a may be caught by and the fixed to a lower surfaceof the flange portion 152.

In the case of the supporting leg 150 (150 a) installed at a center orinside the pallet body portion 110, all of the coupling members 163 maybe lastly coupled and fixed to the fixation members 170 on the honeycombmember 111.

That is, the coupling member 163 for fixing the supporting leg 150 (150a) installed at a center or inside the pallet body portion 110 may beinserted into the lower surface panel 113 and the fixation members 170through the flange portion 152.

The head portion 163 a may be caught by and fixed to a lower surface ofthe flange portion 152.

All of the supporting legs 150 may be detachably fixed to the palletbody portion 110 and the outer frame 120 through the coupling member163.

Accordingly, when some of the supporting legs 150 are seriously damagedand need to be replaced, the coupling member 163 connected to thedamaged supporting legs 150 may be released, the damaged supporting legs150 may be separated, and the new supporting legs 150 may be installedat a corresponding location.

The rib 1512 may be arranged at a bottom surface and an internal wall ofthe cavities 1511 in the unit supporting leg 151 and the plurality ofribs 1512 may be provided to be arranged in the form of ‘#’ as viewedfrom the above, as shown in FIG. 13.

The rib 1512 may enhance strength of the unit supporting leg 151 and maydistribute load.

The flange portion 152 may be arranged on a lower surface of the outerframe 120 or may be arranged below a lower panel of the pallet bodyportion 110.

Accordingly, the lower surface of the outer frame 120 and the flangeportion 152 may form a step difference and, also, the lower surfacepanel 113 of the pallet body portion 110 and the flange portion 152 mayform a step difference.

When the pallets 100 that form a step difference are stacked to formlayers, the pallet body portion 110 at an upper level and the palletbody portion 110 at a lower level may be spaced apart from each other, afork of a forklift may enter this space or a worker may grip the pallets100 to advantageously lift the pallet 100).

That is, in the case of a conventional cumulative pallet, when there isno step difference and pallets form a multilayer structure, there is nogap between pallet body portions or the interval is dense and, thus, afork of a forklift is not capable of being inserted into the gap or theworker is not capable of gripping the pallet and the pallet is notcapable of being easily lifted.

However, according to the present invention, such the gap may be formedto enhance workability for lifting a pallet.

FIG. 16 is an exploded perspective view of the cover member 300.

The cover member 300 may include the cover body portion 310, thesupporting leg support 350 arranged on a plurality of installationportions 311 of a lower surface of the cover body portion 310, and theouter frame 320 that surrounds an outer edge of the cover body portion310.

Although the case in which the installation portions 311 are provided inthe form of groove is illustrated, any structure may be used as long asthe supporting leg support 350 is fixed and coupled (e.g., a protrusion,an uneven portion, and a coupling structure).

The outer frame 320 may include an edge frame 321 installed on an edgeside of the cover body portion 310 and a corner connection portion 322for connecting the edge frames 321 that are arranged in a perpendiculardirection and installed at a corner portion of the cover body portion310.

Here, structures of the edge frame 321 and the corner connection portion322 are similar to structures of the edge frames 121 and the cornerconnection portion 122 of the aforementioned pallet except that theupper accommodation grooves 3213 and 3223 (refer to FIG. 17) arearranged downward.

The installation portions 311 formed on an upper surface of the coverbody portion 310 may not completely penetrate in a vertical directionunlike the through holes 110 a; 111 a, 112 a, and 113 a of the palletbody portion 110 and a portion of an upper surface of the installationportions 311 may be dug down by a predetermined depth.

Accordingly, the depth of the installation portions 311 may be smallerthan the thickness of the cover body portion 310.

When the supporting leg support 350 is arranged on the installationportion 311, a coupling member 173 may be inserted from below to fix thesupporting leg support 350 to the cover body portion 310.

When box assembly structures are stacked as a multilayer structure, thesupporting leg support 350 may support the supporting leg 150 of thepallet of the box assembly structure at an upper layer from shaking inright and left directions.

Accordingly, the supporting leg supports 350 may also be arranged alonginner and outer edges of the cover body portion 310 according toarrangement of the supporting legs 150.

Like in the case in which one supporting leg 150 is divided into aplurality of unit supporting legs 151, one supporting leg support 350may also be divided into a plurality of unit supporting portions 351 andeach of the unit supporting portions 351 may be separated from eachother by a separator 352.

Here, as a representative example, the unit supporting portion 351 maybe configured in the form of a groove but any form (e.g., a protrusionor an uneven portion) other than a groove may be used as long ascoupling with the unit supporting legs 151 or movement of the unitsupporting leg 151 is limited.

Accordingly, the number of the unit supporting legs 151 included in onesupporting leg 150 and the number of the unit supporting portions 351included in one supporting leg support 350 may be the same.

Here, although the case in which the separator 352 is formed as a cross(+) is illustrated, the present invention is not limited thereto.

FIG. 17 is a more detailed exploded perspective view of FIG. 16.

The cover body portion 310 may be formed of a plurality of stackedsheets of plywood, wood plates, or plastic plates. However, the coverbody portion 310 may be formed of staves and, also, may be formed of anupper and lower panel that covers a honeycomb member and upper and lowerportions thereof like a pallet.

However, FIG. 17 shows the case in which a plurality of plates isstacked.

The installation portions 311 may be formed on an upper surface of theplates and, for example, one installation portion 311 may be installedat a center, four installation portions 311 may be installed at cornerportions, and four installation portions 311 may be installed atintermediate portions of an edge.

This may be variably changed according to the size of a box assemblystructure and the size of a cover member.

Insertion holes 312 may be formed in edge portions of the installationportions 311 and may be holes into which the coupling member 173 (referto FIG. 16) for fixing the supporting leg support 350 is inserted, whichwill be described below in detail with reference to FIGS. 18A and 18B.

The edge frame 321 may be arranged at an outer edge of the cover bodyportion 310 and the corner connection portion 322 may be formed in acorner space between the edge frame 321 and the edge frame 321.

As described above, a structure of the edge frame 321 installed on thecover member 300 is similar to the edge frames 121 of a pallet and thecorner connection portion 322 installed on a cover member is similar toa structure of the corner connection portion 122 of the pallet.

That is, the edge frame 321 may include an external wall 3211, aninternal wall 3212, the upper accommodation groove 3213 formed betweenthe external wall 3211 and the internal wall 3212, and an upper wall3214 formed above the upper accommodation groove 3213.

The edge frame 321 may include an upper extension 3215 a and a lowerextension 3215 b that extend inward (in a direction toward a cover bodyportion) from upper and lower surfaces of the internal wall 3212 and aninsertion space 3215 into which an edge of the cover body portion 310 isinserted may be provided between the upper extension 3215 a and thelower extension 3215 b.

A first boundary region 321 a that is inclined (tapered) and a secondboundary region 321 b connected to the first boundary region 321 a andarranged in a horizontal direction (in a direction perpendicular to anextension direction of an edge frame) may be provided at opposite endportions of the edge frame 321.

The first boundary regions 321 a of the edge frame 321 of the covermember 300, which are adjacent to each other, may contact each otherlike a connection structure of the edge frames 121 of the pallet 100

In the cover member 300, a space portion may also be formed in theexternal wall 3211 and the internal wall 3212 of the edge frame 321 andthe space portion of the internal wall 3212 may include a first spaceportion and a second space portion which are separated by a separationrib.

A fixation portion into which a coupling member 183 for coupling thecorner connection portion 322 and the edge frame 321 is inserted andfixed may be formed in the separation rib and the fixation portion mayalso have a C-shape like the fixation portion 1212 d of the edge frame121 of the pallet 100 but the present invention is not limited thereto.

The corner connection portion 322 of the cover member 300 may alsoinclude an external wall 3221, an internal wall 3222, a lowerinstallation portion 3223 between the external wall 3221 and theinternal wall 3222, an upper wall 3224 above the installation portion3223, and a protrusion 3225 formed on a lateral surface of the internalwall 3222 and coupled to a lateral surface of the edge frame 321.

An external insertion hole may be formed in the external wall 3221 andan internal insertion hole may be formed in the internal wall 3222, thecoupling member 183 may be inserted into the external insertion hole andthe internal insertion hole, and the corner connection portion 322 andthe edge frame 321 may be lastly connected.

All the detailed configurations and coupling relations are the same asthose of the corner connection portion 122 of the pallet 100 and theedge frames 121 of the pallet 100 shown in FIGS. 10 to 13 except thatthe upper accommodation groove 3223 of the corner connection portion 322and the upper accommodation groove 3213 of the edge frame 321 are formeddownward and, thus, a repeated description will not be given here.

Accordingly, goods may be moved using the box assemblies 1 for deliveryand, then, the box assemblies for delivery may be disassembled using themethod of FIG. 21 and may be packaged and returned using the method ofFIG. 22.

According to the diverse exemplary embodiments of the presentdisclosure, a pallet body portion includes a honeycomb member and, thus,load-bearing may be remarkably increased.

An upper panel and a lower panel may be arranged on an upper surface anda lower surface of a honeycomb member to smoothen most of an externalsurface, thereby stably supporting goods.

When a supporting leg is detachably arranged on a pallet body portionand a supporting leg breaks and does not perform its function any more,only the corresponding supporting leg may be replaced and a pallet maybe continuously used.

A supporting leg includes unit supporting legs that are separated fromeach other and, thus, supporting force may be doubled due to loaddistribution. When some unit supporting legs break, the remaining unitsupporting legs may function as a support and, thus, even if somesupporting legs break, the other supporting legs may perform a stablesupporting function.

Conventionally, a pallet manufactured via injection molding and a baseboard thereon are used. However, according to the present invention, abase board is omitted and an upper surface of a pallet functions as thebase board and, thus, a structure of an assembly box structure may besimplified.

A flange of a supporting leg is supported by a lower surface of a palletbody portion and, thus, load may be distributed and a supporting legflange and a fixation member in the pallet body portion may be coupledby a coupling member, thereby providing a stable coupling structure.

In particular, when the fixation member is a rigid fixation structuresuch as a metal insert, the coupling member may be more stably fixed.

Edge frames and a corner connection portion for connecting the edgeframes are used at an edge of the pallet body portion, therebypreventing an edge portion of a pallet from breaking due to collision,etc.

An accommodation groove may be formed in an outer edge and a lower edgeof a box may be inserted into the accommodation groove to allow the boxto be more stably positioned on the pallet.

In addition, the corner connection portion may connect edge frames thatcross each other to achieve entire structural stability of an outerframe and to enhance impact resistance.

In the case of a cover member, a supporting leg support may be arrangedon an upper surface of the cover member and, thus, when box assembliesfor delivery are arranged as a multilayer structure, a more stable statemay be maintained.

In addition, a coupling member for coupling a supporting leg support ofa cover member may not be externally exposed and, thus, interferencebetween the coupling member and goods in the box may be completelyprevented.

Edge frames and a corner connection portion for connecting the edgeframes may be used at an edge of a cover body portion and, thus, aproblem in that an outer portion of the cover member breaks due tocollision, etc. may be overcome.

An accommodation groove may be formed in an outer edge and an edge of anupper surface of a box may be inserted into the accommodation groove tostably position the cover member in the box.

In addition, a corner connection portion may connect edge frames thatcross each other to achieve entire structural stability of an outerframe and to enhance impact resistance.
